Description:Alloy 825 (UNS N08825) is an austenitic nickel-iron-chromium alloy developed for exceptional corrosion resistance in both oxidizing and reducing environments. It was developed to provide exceptional resistance to numerous corrosive environments, both oxidizing and reducing.
The chromium and molybdenum content of Alloy 825 provides resistance to chloride pitting, as well as resistance to a variety of oxidizing atmospheres. It is resistant to corrosion in a wide variety of process environments including sulfuric, sulfurous, phosphoric, nitric, hydrofluoric and organic acids and alkalis such as sodium or potassium hydroxide, and acidic chloride solutions.

Spiral Wound Gasket Alloy 825 Applications:
